Patented April 1907.

Application filed September 12. 1906. Serial No. 334,249-

To all whom it may concern:

Be it known that I, CHARLES ORVILLE WVRIGHT, a citizen of the UnitedStates, residing at Bluefield, in the county of Mercer and State of WestVirginia, have invented a Shipping-Case, of which the following is aspecification. p

This invention is an improvement in shipping cases, and relates moreparticularly to a form of case or crate especially adapted for use inthe transportation of grinding rolls of that class which are employed inconnection with flour mills, and the principal objects of the inventionare to provide a light, strong and durable casing or crate of thischaracter which will inclose the roll and thoroughly protect thegrinding surface thereof, and so that said roll will not become injuredin the transportation of the same from one place to another, as forinstance from the manufacturer to the mill.

A further object of the invention is to construct the shipping case insuch manner that the same may be readily applied to the grinding roll,and so that the arts of said case or' crate may be separate .and closelypacked for storage or shipment back to the manufacturer.

Other though minor objects of the invention will hereinafter appear inthe specifications, and what I claim as my invention and desire tosecure by Letters-Patent will be more particularly set forth in theappended claims.

In the accompanying drawings, which form a part of this specification:Figure 1 is a sectional view through a shipping case or cratecgnstructed in accordance with the invention,- and showing the aplication of same to the usual form of grin g roll. Fig. 2 is a detailperspective view of the envelop or outer case. line 33 of Fig. 1. Fig. 4is a view showing a modified. form of shipping case made in practicallytwo sections, the near section bemg removed Fig. 5 is anend view of themodification'shown in Fi 4. Fig. 6 isga sectional view on the line 66 ofFi 4. Fig. 7 is a perspective view of one endof th modified form ofshipping case.

Both forms of the shipping case shown in the drawings are .ada ted toreceive the grinding roll 1 and its s iaft 2, which are employed inconnection with flour mills, and as rolls, especially the shafts, are ofa standard length-the shipping case may be Fig. 3 is a sectional view onthe made of a standard size, allowing for slight adjustment only.

As shown on Sheet 1 of the drawings I employ primarily two disksS and 4,each comprising two parts or halves provided centrally with an openingthrough which the shaft 2 passes, the said. opening having a surroundingannular boss 5 externally threaded to receive a threaded collar 6, bywhich latter said parts of the disk are connected together, it beingunderstood, of course, that each part of the disk has a half-boss whichtogether form the aforesaid annular boss.

- The two parts or halves of each disk are connected to thecorresponding or companpendently, by means of turn-buckle devices eachcomprising in the present instance a tube 7 internally threaded at itsends to receive the oppositely threaded bolts 8, the latter engaging theopen-ended slots 9 in the edges of the aforesaid disks 3 and 4, and theends of said tube are preferably squared to receive a wrench for turningthe same. It will be seen, therefore, that when the parts of the disksare brought together on the shafts and connected by the threaded collars6, said disks may be adjusted with respect to the ends of the roll byturning the tubular members of the turn-buckles.

For the purpose of protecting the ends of the shafts 2, and to moresecurely hold the ploy two circular plates 10 10, one for each the disksby means of the rods or olts ll. The plates 10 are bulged centrally toprovide a recess 12, and in said recesses are seated the ends of thegrinding-roll shaft, the connection being further au mented by screws13, which pass through the center of the plates with, as in use thegrinding-roll is very firmly held in place. Over the disks, so as tocover the grinding-roll, is placed a protecting case ion parts or halvesof the other disk, hide-- grinding-roll between the disks 3 and 4 Iemend of the shaft, and connect said lates to into the usualcentering-recesses in the ends ever, these packing devices may bedispensed tion witlia removable rod 19.

or envelop 16, consisting of the two semi-.

circular sections hinged together at one edge,

as at 17, and connected together by the interlocking ears on the otheredge in conjunc- I In applying this form of shipping case to thegrinding roll the two sections, each'comprising the place by engagingthe bolts with the slots in the edges of: the disks and tightening saidbolts to bring'the plates against the ends of the shaft, and, finally,the protecting case or envelop is applied and securedby the rod 19.In'case the rubber rings are employed they are, of course, slipped overthe ends of the shaft-before. the parts of the shipping case are aplied.

In the orm, of shipping case shown on Sheet 2 of the draw ngs anlnclosing case is provided'consisting of racticallytwoparts or sectionsand 21, W ic'h are placed on 0pposite sides of the roll and shaft andbolted together, having the meeting flanges 22 through which the boltspass. Each section comprises the semi-cylindrical portion 23, embracingthe grinding-roll, the semi-circu lar heads 24, bearing against theends'of said roll, and the semi-tubular portions 25 formed integrallywith the heads and embracing the projecting ends of the shaft, saidsemitubu lar portions being threaded at their outer ends to receive the,caps 26. The semi-circular portions 23 are formed in two parts, as shownin Fig. 4, the meeting edges of said parts overlapping and connected byclamping-bolts 27 passed through ears 28 formed on the respective parts.The heads of the inclosing case may be brought directly against the endsof the grinding roll, but it is preferred to employ a fillin disk 29 ofyielding material which will ta e up any jar; such filling disks beingalso employed for the purpose of occupying the space which would be leftin case the grinding-roll is shorter than the standard size.

The heads of the cylindrical part otthe shipping case are extended toprovide a flange 30, the outer edges of which are preferably beyond theplane of the ears 28, so that such shipping caseand its contents may berolled over the ground or floor from one place to another. Theconnection of the heads 24 and tubular portions 25 is preferablyreinturer to the mill, and as the parts of the shipping case are allmade of metal the same ma be used over and over again.

Having thus described I claim as new and desire to secure byLetters-Patent, is
